Crash dump OpenVMS on lock manager

Toine_1 — Fri, 07 Aug 2009 12:39:29 GMT

Hi,

Has anyone had this problem before?
During a reboot of a Alpha server with OpenVMS 8.3 I got this crash dump.
Is this a software problem or a hardware problem.

15:23:27 ** OpenVMS Alpha Operating System V8.3 - BUGCHECK ****

Re: Crash dump OpenVMS on lock manager

Seems to be software , see here R0 = 00000000.00000124 %SYSTEM-F-INSFMEM, insufficient dynamic memory

Have you tried autogen to see if any parameters need adjustment? My best guesses are NPAGEDYN or LOCKIDTBL.

I would also do a SDA> show memory/pool

Re: Crash dump OpenVMS on lock manager

Volker Halle — Sat, 08 Aug 2009 10:02:47 GMT

Toine,

you've hit some resource problem in the lock manager. The lock manager does not use nonpaged pool much. It has it's own pool zone in S2 space (for LKBs, RSBs etc.).

See a similar case in ITRC:

http://forums11.itrc.hp.com/service/forums/questionanswer.do?threadId=997728

This is a software problem. It could occur during lock remastering, when a huge lock tree is being moved to the newly booted local node.

If you want a detailled analysis, explanation and guidance on how to prevent this from happening again, you owuld have to escalate this crash to HP.

Volker.
